After making herself at home in the dojo, Master Yo thought it would be a good time to introduce Bi to the rest of the Woo-Foo Warriors, especially Lena, whom Bi has saved earlier.

"Kids, this is Bi Bai Tan," Yo motioned to Bi before looking back at the other kids. "She'll be staying in our dojo for a while."

Bi flipped her sleek hair back, smiling at her new friends, a tinted blush formed on her face. "Hello..."

"Wow..." Dave muttered under his breath before gently bumping an elbow to Coop's side. "She's pretty..."

"I b-b-buck-know..." Coop muttered back, pulling down his dark shades to get a better look at her.

"Hey, nice to finally meet you," Lena said as she took a step forward and offered her hand to Bi. "I'm Lena. You saved my butt earlier."

"Glad to have done it," Bi smiled as she shook her hand. "And don't worry, the worst thing that could possibly have happened to me could've been getting my hair in a frizz."

"Oh, I know getting bad hair is a key ingredient in ouch," Lena laughed with a cool, sassy tone.

"So you guys are Woo-Foo Warriors..." Bi began as she gaze at the colorful group of kids. "Wow, Master Yo really trained you well..."

"Actually, I did," Yang said proudly, having stepped forward next to Bi a little too closely. "I guess you can call me the next master if you will..."

"Oh, please..." Yin rolled her eyes.

"Really?" Bi raised a delicate eyebrow at him.

"Well, yeah..." Yang wiggled his eyebrows at her.

"And did I mention I'm Yang's girlfriend?" Lena interrupted, a little too loudly, her gaze cutting into Yang like a knife. Yang shuddered under her gaze.

"Wow, lucky you..." Bi whispered to Lena. "He's pretty cute."

After the others introduced themselves to Bi, it was now time for some training as Master Yo brought them outside into the obstacle course. Bi watched in amazement as the other kids tackled, chopped, and burned anything that was in their way. She especially watched Yang and Coop as joined hands and Coop used Yang as a battering ram to knock down a few wooden standees.

"Wow..." Bi muttered under her breath.

Coop looked up just in time to catch her watching him. He smiled at her and waved...and ended up accidentally hit by Dave from behind. Bi winced at the impact he received.

"Sorry..." Dave muttered as he got up.

"You want to try?" Bi turned to see Roger Jr. stand beside her, motioning her to the obstacle course.

"Oh, I'm not really sure..." Bi pondered for a moment. "Okay!"

And with that said, Bi stepped into the course. Then she held a fighting position...she let out a battlecry and attacked.

She almost seemed like a blur as she attacked wooden standees left and right, sending a powerful punch or high-kick to anything that came in her way.

"Wow..." Yang muttered under his breath, watching as she broke another one in half.

Then suddenly, Bi waved her hands in the air gracefully. And a blue orb of light shone above her.

"Magic, too?" Yin exclaimed. "Double wow..."

Bi let out another cry before she blasted over a dozen standees high into the air before they came back down to the ground in pieces.

Master Yo stood by, observing Bi's skills. She seemed as skilled as the children, and it seemed that she had been training before. The elderly panda folded his arms, giving an approving nod, not sure what to say to encourage the young, raven-haired girl.

Finally, Bi was finished as she stood her ground, panting heavily. She smoothed her hair before smiling at her dumbfounded friends.

"That..was...awesome!" Yang exclaimed raced over to her. "It's like looking at a mirror..." He said in an awestruck voice as he gazed at her with sparkling, admirable eyes. "Well, not exactly looking at a mirror...I mean...well, the reflection is much better, if you know what I mean..."

"Oh, I think I know exactly what you mean..." Bi chuckled as she gave him a wink.

Yang nearly lost the balance in his knees as he just gazed at Bi with a lovesick grin...until he felt a warm hand on his back. He turned to see it was Lena, who was trying her hardest to smile at Bi, despite the aggravation familiar in her expression.

"You're really good..." Lena muttered through clenched teeth.

"Hey, you guys are the real deal around here," Bi told them modestly. "Just trying to follow in you guys' footsteps!"

Suddenly, they ground began to shake as the children turned to see something dark emerging from the streets of town. The shadow soon formed into visible color, revealing a demon with four arms.

"Who is that?" Bi exclaimed as she came closer to the person nearest her.

"The Night Watcher..." Yo growled as he cracked his knuckles. "Ferocitus!"

"The most evil Night Master of all time!" The demon cackled.

"Also the most childish!" Yo shot back with a smirk.

"H-hey!" The demon retorted, hurt by the insult. "That's mean to say, you jerk!"

"Wow, he's actually not that scary anymore..." Bi said as she placed a hand on whomever she was next to."

"Uh, buckaw..." Bi turned to see her hand was on Coop's shoulder, and that her front was pressed gently to him from behind. Her eyes widened as she stepped back, face flushed.

"If you're looking for feathers, I'm your chicken!" Coop bucked, flashing her a smile.

Bi just smiled at him, blushing, until Yin got between them and held her hands out, ready to fight the Night Master. "Get him!"

And with that said, everyone, minus Bi, jumped up and assaulted the Night Master. Bi could only stand there as she watched her friends give everything that had as they tried to take down the person that was harming their home.

"Go, Coopy!"

Bi turned to see a few adults stand behind her, cheering the kids on. One of them looked like a grown, woman version of Coop.

"Are you Coop's mom?" Bi asked her.

"Yes, I am," she said proudly. She eyed her, smiling. "Are you my son's second girlfriend? Because you're pretty enough to share my son with the pink bunny!"

Bi blushed, then jumped back as Yin was knocked to the ground between her and Coop's mom.

"Yin, are you okay?" Bi cried.

"Oh, yeah..." Yin muttered as she shook her head. "That's going to take some brushing..." Yin smoothed the top of her ears before she angrily let out orbs of magic toward Ferocitus.

"Let me help!" Bi insisted as she stood beside the pink rabbit and held her hands out. Orbs of light let out threw her palms and she let out another battlecry as she moved forward.

She butted her head into the chest of Ferocitus.

"Hey, that hurt!" Ferocitus whined, rubbing his chest.

"Oh, you really need to hide your feelings..." His bat sighed.

"Huh, she's pretty good..." Coop's mother said. She turned to Yin. "Looks like you've got some competition."

"No one's stealing Coop from me..." Yin muttered, trying to keep her voice low from a growl.

Master Yo leaped forward, sending his fist straight across Ferocitus's jaw, sending him to the ground. "This is too easy..." The panda chuckled, cracking his fists.

"Oh, that does it!" Ferocitus growled, losing his child-like demeanor before he smoothed the top of his head. "Prepare for darkness!" He turned to his bat. "That's you cue!"

"Yes, master..." His bat sighed before he flapped over to the ground where they had emerged. "Hey, you lazy bums!" He called into the hole. "Get up here! Time for work!"

"More monsters?" Yang chuckled. "Oh, bring it on!"

His excited expression turned to one of dumbfounded as the 'monster's emerged from the ground.

Long, dark shadows floated into the sky, creating a swirling whirpool of darkness, thus turning the bright sunny sky into one of frightening dark night.

"The dark is scary..." Dave muttered as he felt his wooden body shake.

"Oh, no, he's serious..." Master Yo grumbled.

"What's going on?" Yin demanded.

"Ferocitus just might be as good as the other Night Masters..." The panda went on. "Unlike them, this dude has a pretty good plan..."

"A plan to wipe out Woo-Foo!" Ferocitus cackled as the darkness suddenly merged down to the ground. It spread through the streets, darkening anything in its path. Even people

Roger and Dave fearfully braced for impact as the shadow headed towards them. But it passed them...

...and hit their parents.

"Mom!" Coop cried.

"Daddy!" Lena screamed.

The adults tried to fight off the shadows, but the force was too strong, and soon, they were completely engulfed in the darkness, showing nothing but their whited-out eyes.

"Are they...?" Bi's voice cracked as she turned to Master Yo.

"No..." The panda muttered. "Ferocitus's got something better..."

Finally, those whited-out eyes glowed into deadly red...and the adults and every other person in town that had been hit by the shadows let out a deadly, beast-like scream.

"Holy cow!" Yang cried. "That actually makes you want to pee your pants right now!"

"Been done..." Jobeaux muttered as he checked his shorts.

"Oh, eww..." Yin cringed.

The shadow demons stood tall, then grew higher than the buildings themselves. Every demon sprouted sharp claws, sharp teeth, and huge feet. They stood in order as the Night Master approached them as if he were an army general and they were his new recruits.

"Very nice..." Ferocitus said with a nod. Then he looked over at Dave's parents. "Uh, these still look like trees..."

"Better than nothing, master..." His bath sighed.

"Oh, well..." Ferocitus shrugged as he reached over and took a small piece of wood from Dave's mother's bushy hair and used it as a toothpick.

"Get away from my parents!" Dave shouted angrily before he jumped forward and intended to attack him.

But before he could reach the Night Master, Dave's father stood in the way and slammed Dave down to the ground.

"D-dad?" Dave whimpered, unable to believe his own father had attacked.

"Praise Ferocitus..." His father droned, his shadow exterior making him look more demon than plant. "All must bow before him..."

"No..." Dave protested, devastated that the Night Master had full-control of his parents.

Finally, the other shadowed slaves came forward, intending to attack the Woo-Foo Warriors.

"Come on, Dave!" Bi urged before she picked up the stump kid and they all retreated.

"Run, cowards!" Ferocitus cackled. "Run like rats!" He cackled even louder...then began coughing.

His bat sighed. "Another cough drop?"

"Thanks."
_

At the dojo, Master Yo peered through his mail slot, seeing how much more damage Ferocitus had done to their town. Everything was dark, lifeless, and fearing. The elderly panda sighed before he gazed back toward the children.

All were devastated that their parents had fallen under the spell of the Night Master, but none were as devastated as Dave, whom whimpered as he lay on the couch, being comforted by Bi and Yin.

"M-mommy..." He whimpered, trying to hold the tears. "D-daddy..."

"We'll get them back," Yin assured him. "We always win."

"But you got to admit," Lena said. "This dude is actually something. Though he's a total baby, he is the real deal, ya'll."

"Not helping..." Roger muttered to her through clenched teeth as he kept his eye on the whimpering stump kid.

"Master Yo..." Yang began, his feelings of hate and anger replaced by concern and fear. "What do we d now?"

The elderly panda gazed at his son. He was always so brave and in-control and always came up with a plan...but now the Night Master really scared him.

Yo sighed. "Make everyone some tea..." He told him before he walked off. "I'll be in my room."

As Yang did as he was told, Bi watched as the elderly panda just walked off. Unable to fight off her worry as well as her curiosity, the young girl slowly followed behind him, keeping quiet.

Bi slowly poked her head through the slightly opened door and found the elderly panda sitting at the end of his bed, lost in thought. He seemed to have something in his hand.

Bi couldn't hold her concern anymore as she lightly coughed.

The panda turned to see her standing in his doorway. "Oh, hello, Bi..."

"Master Yo..." She began softly. "I know that everything is going downhill...but we just got to keep strong."

"Ah, your mother must have taught you well..." The panda chuckled half-heartedly. "That's exactly what I tell my students."

Bi slowly approached him, then she looked down at his hands.

It was a ring.

"What's that?" She asked curiously.

Yo gazed down at the ring, then sighed sadly. "It's my wedding ring..." He looked up into space. "Just recently, my memory had come back and I had found out Yin and Yang were my children...but I received no memory of their mother." He held the golden ring up. "Now I know this ring wasn't some fashion trend from my time...it's actually the symbol of a marriage I can't even remember..." He dropped his head in shame.

Bi gazed at the ring, then back at Master Yo. She felt truly bad for him...

"I never knew my dad..." She confessed quietly.

The panda turned to her. "Really?"

"Yeah..." Bi sighed. "My mom told me something bad happened to my dad the day I was born...that he might be dead. I was really sad. But maybe..." She lowered her gaze. "Maybe he might still be alive. I mean, both my mom and I are hurt by the loss of so many years, but we might actually keep up hope..."

Yon chuckled, before patting her back. "Your mother's quite strong if she's anything like you."

"Oh, we're definitely alike," Bi nodded. "I got my mother's hair! And pretty looks!"

"Yeah, your father must be pretty lucky..." Yo sighed before gazing down at his ring once again. "I keep remembering that my wife is just so beautiful...but I can't even remember her face..."

"I'm sure the memory will come back, Master Yo..." Bi assured him gently.

Yo sighed before he placed the ring back in a special box, entitled 'Lost Memories'. "Yeah, I hope so..."
